Abahlinzeki bemishini yempendulo yamandla e-frequency converter bakukhumbuza ukuthi ekukhiqizweni kwansuku zonke, izinjini zemishini yokulawula izimboni zivame ukonakala ngenxa yokusebenza okungalungile, okungaphumeleli nje kuphela ekulahlekelweni kwezimali kodwa futhi kunomthelela omkhulu ekuqhubekeleni phambili kokukhiqiza. Ukusetshenziswa okulungile kwama-converter ama-frequency kungaba nomthelela omuhle ekuvikeleni ama-motor.
1. Ukuvikelwa kwe-inverter ngokwayo:
I-overcurrent esheshayo, i-overvoltage, i-undervoltage, i-overload, i-short circuit to ground, kanye nesekhethi yokulawula engavamile konke kuvikelwa yi-inverter ngokwayo. Imikhawulo isethelwe i-overcurrent, overvoltage, undervoltage, njll. Uma inverter isebenza, uma idlula umkhawulo, ngisho nesikhathi esifushane, izodlala indima yokuvikela. Umsebenzi wayo wokuvikela ukumisa okukhiphayo, okusho ukuthi i-terminal ephumayo ye-inverter ayinayo i-voltage. Lona umsebenzi wokuvikela we-inverter. Umsebenzi wayo wokuvikela ubucayi futhi uzwela kakhulu. Ukuze uvikele i-inverter circuit kanye ne-rectifier circuit ngaphakathi kwe-inverter, ibucayi kakhulu, engabangela kalula ukuhamba njalo. Njengoba sonke sazi, ukuhamba njalo kubalulekile ekukhiqizeni kwethu. Kubi kakhulu, ngakho-ke kufanele sithathe izinyathelo ezithile zokuvikela i-inverter ngokwayo, Ukwazi ukugwema ukukhubeka esimweni esithile yilokho esizoxoxa ngakho ngezansi.
2. Ukuvikelwa kwezinjini zikagesi:
Isivikelo esiyinhloko samamotho kagesi ukuvikelwa kwe-electronic thermal. Inkinga enkulu ngamamotho ethu kagesi ukukhiqiza ukushisa. Uma i-motor ishisa, kulula ukushisa ungqimba lwawo lwe-insulation, okubangela ukujikeleza okufushane ekujikeni kwayo futhi kubangele ukujikeleza okufushane kuwo wonke umsinga. Ngakho-ke, ukuvikelwa okuyinhloko kwama-motor kagesi ukuvikelwa kwe-electronic thermal. Ngakho-ke, ake sethule ukuvikelwa kwe-electronic thermal ngokuningiliziwe.
3. Ukuvikelwa kohlelo:
Ukuvikelwa kwalesi simiso kuhlobene nokuvikelwa kwe-inverter ngokwayo, okubucayi kakhulu. I-overcurrent encane noma i-overvoltage ingabangela lokho esikubiza ngokuthi uhambo. Ukusabela kulesi simo, semukele ukuvimbela itafula, ukuqalisa kabusha okuzenzakalelayo, nemisebenzi yokuvikela ipharamitha, konke okuyimisebenzi yokuvikela yesistimu. Lokhu kuvimbela i-stall kanye nokuqalisa kabusha okuzenzakalelayo kuhloswe ezimweni lapho isiguquli semvamisa sizwela kakhulu, ukuze kwezinye izimo, nakuba sidlula inani laso elilinganiselwe, asikwazi ukukhubeka, noma uma kwenzeka kunqamuka ugesi, singaqalisa kabusha ngaphandle kokubangela ukuba umugqa wonke wokukhiqiza ume. Lokhu ukuvikela isiguquli semvamisa ngokwaso. Kukhona nomsebenzi wokuvikela ipharamitha: umsebenzi oyinhloko we-converter frequency ufinyelelwa ngokusethwa kwepharamitha kanye nesekethe ye-voltage port. Ngakho-ke, uma sesiyibekile imingcele, indlela yokuvimbela ukuthi ingaphazanyiswa noma ilahleke ngabanye futhi kuwukuvikela kwalo lonke uhlelo.
